Guitar Hero III

I have been so excited to play the Hoyt's new Guitar Hero III. I've been keeping the XBOX360 and the Guitar Hero at my house for a month or two now so her kids wouldn't see it before Christmas. I've been so tempted to plug it all in and play it - Just to make sure it worked! Well, today I had the chance to go to their house and play it for a while. I couldn't put it down, and got frusterated when Sarah (who's 12) got extended play time before I could go again - NOT GOOD! That is why we don't have a game system at our house - I would play it. I'm not into the other games that much, but I LOVE this Guitar Hero stuff. Is it so sad that I can't wait to get back over there and play that game!!!!!?????
